The present invention relates to an electric connector member to supply electrical energy into an electric igniter of the type which includes a priming charge ignitable by heat generated when feeding an electric current through the resistive element of the igniter and which igniter must be protected against accidental ignition caused by electromagnetic or static electricity which may enter into the igniter through the feed wires. Instead of providing the igniter itself with a high frequency filter, which requires a large space, the connector member is provided with such a filter (16, 17). This makes it possible to reduce the outer dimensions of the igniter to a great extent with the protection against accidental ignition maintained. Further the need to provide each of the igniters with a specific high frequency filter, designed for the expected interference condition in the actual application, does no more exist.
